Abstract (en)
[origin: EP0198151A2] Catalysts for polymerization and copolymerization of olefins to form polymers having both a high degree of isotacticity and fast rate of crystal transformation. The catalysts embody a component made by chlorinating a magnesium alkyl with chlorine or a mixture of chlorine and alkyl chloride to form a carrier, contacting the carrier first with liquid TiCl<sub>4</sub>, then with a Lewis base, and after that at least once with TiCl<sub>4</sub> in the absence of Lewis base.
